A reaction work-up for an aqueous reaction mixture calls for extraction first with diethyl ether and then a wash with saturated aqueous sodium chloride. What two functions does the the saturated sodium chloride wash serve? (usually Brine is not added to the aqueous solution during the first extraction) Group of answer choices It pulls water from the organic layer to dry it. It helps force the organic compound into the organic layer. It degasses the solvent It changes the color...

Extraction of benzoic acid and 9-fluorenone using diethyl ether. (please do not include ethyl 4- aminobenzoate). I have to create a flow chart to diagram the key steps of the experiment and isolation of products. 0.100g of benzoic acid and 9-fluorenone are dissolved in diethyl ether. The extraction solvent is 5% sodium hydroxide (to extract the acidic component from the organic phase). Saturated sodium chloride is added to the organic layer. drying the organic solution: anhydrous sodium sulfate is added...

Extraction Q1. Why doesn’t the neutral organic compound dissolve in the 1.5 M NaOH solution? Q2. Why is diethyl ether a good choice for the organic solvent in this extraction experiment? Q3. What experimental difficulty would you encounter if you neglected to include the drying step before evaporating the ether solution of the neutral organic compound? Q4. Why are the two organic compounds recrystallized before their melting points are determined? Q5. What IR bands are most useful in distinguishing a...

Suppose solute A has a distribution coefficient of 1.0 between water and diethyl ether. Demonstrate that if 4.0 mL of a solution of 0.20 g of A in water were extracted with two 1.0-mL portions of ether, a smaller amount of A would remain in the water that if the solution were extracted with one 2.0-mL portion of ether.
